GATE ECE 2006 | Question: 80
Statement for Linked Answer Questions 80 and 81 Consider the following Amplitude Modulated (AM) signal, where $f_{m}<\mathrm{B}$ \[x_{\mathrm{AM}}(t)=10\left(1+0.5 \sin 2 \pi f_{m} t\right) \cos 2 \pi f_{c} t\] The average side-band power for the $\text{AM}$ signal given above is $25$ $12.5$ $6.25$ $3.125$
